PHILADELPHIA (AP) — An animal training center inspired by canine rescue work on 9/11 is graduating its first class of working dogs.

The University of Pennsylvania’s Working Dog Center held a commencement ceremony Tuesday for a yellow Labrador retriever named Socks.

The canine is going to work for the campus police force performing duties including bomb detection.

Other animals in the class will be working as medical alert dogs or on urban search-and-rescue teams. They gave demonstrations of their search skills and showed off their agility on an obstacle course.

The Working Dog Center, which is part of Penn’s veterinary school, began training puppies in Philadelphia on Sept. 11, 2012.

They are named after dogs who worked at ground zero during the terrorist attacks in 2001.
